1:43 scale. The Holden VN SS Group A was an exceptional Australian muscle car which was built under contract by HSV for General Motors Holden Australia and was released in the month of November over twenty years ago in 1990. This car has the honour of being described as the last Group A model to be produced by General Motors Holden Australia due to changes in CAMS regulations and in addition to that title, it also carried the mantle of being the most expensive HSV ever released at that time. This model will be produced in high quality resin.
